Former President Trump has turned the Republican presidential primary on its head within four months, turning a 14-point deficit to Florida Gov. Ron DeSantis into a 13-point lead, in a new Wall Street Journal poll released Friday.

Trump now leads DeSantis 51% to 38% among likely GOP voters, according to the Wall Street Journal poll.

DeSantis has not officially announced his intention to run for president in 2024, but he is expected to launch a campaign sometime after the end of Florida's legislative session, which concludes next month. Behind the scenes, DeSantis has already made plenty of moves toward launching a campaign, including beefing up staff in Tallahassee, Florida.

Trump, who launched his third straight White House campaign in November, has seen his status as the GOP front-runner solidify in recent polling, especially after Republicans rallied around him as he became the first former president in American history to be indicted. 

Trump has cashed in on the legal controversy, with his campaign raising millions since news of the indictment broke the evening of March 30.
